Comparative study of micro hydro model systems for powering the sub-village of Tulaun Lalumpe Minahasa of North Sulawesi Province, Indonesia

Abstract

In this work, we conduct a comparative study to meet the energy demands of a rural village in Indonesia, Tulaun Village, Lalumpe, Indonesia. We utilize different scenarios of rural power systems based on four models of the micro hydro system. The first model of energy-independent village is 100% micro hydro supply. The second model is a combination between micro hydro and the grid. The third model is a combination of micro hydro, grid, and diesel. The fourth model is a combination of 3 sources that consists of micro hydro, solar PV, and battery. The load demand data were obtained based on the communities’ electricity needs of 55 households in the village. The Hybrid Optimization Model for Renewable Energy (HOMER) was selected to analyze this techno-economic feasibility study. The best option is the fourth model based on the result in terms of the cost of electricity (COE), and environmental emission consideration.
